APPARATUS FOR COOLING CYLINDERS OF EXPLOSlVE-ENGINES.

SPECIFICATION forming part oi Letters I'E atent N 0. 689,568, dated December 24, 1901. I Application filed January 5, 1901. Serial No. 42,155. (No model.)

To all whom, it may concern? Be it known that I, JOHN A. SEOOR, a citizen of the United States, residing in the bor-' ough of Brooklyn, in the city of New York, in 5 the State of New York, have invented certain new and useful Improvements in Apparatus for Cooling the Cylinders of Explosive-Engines; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the ac-.

companying drawings, making a part of this specification, in which- Figure 1 is a side elevation and partial sectional view of an apparatus comprising my views of the three-way cock whichis one of the elements in the mechanicalcombinations embraced in my invention, said views illustrating different positions of the cock in the use and operation of the invention.

My invention relates to explosive-engines in which the explosion-cylinder is kept qool to the requisite degree by a circulation of water through a chamber or chambers provided to the cylinder.

3o chamber of the engine-cylinder back to and through the supply-tank and so on continuously and whereby also provision is made for the easy and convenient withdrawal of the cooling liquid from the tank alone, from the cooling-chamber alone, or from both tank and chamber, as occasion may require.

A'is the cylinder of an explosive-engine, which may be of any preferred type and construction so long as the cylinder is provided 40 with a cooling chamber or chambers to receive a liquid of comparatively low temperature to keep down the temperature of the cyl inder to a proper degree when subjected to the heating action incident to the operation of In Fig. 1 of the drawings the cooling-chamber is indicated at a,the surrounding outer portion of the cylinder being shown as broken away to reveal said chamber. Any preferred structure of the chamber and any so desired relation thereof to the bore or walls Figs. ,2, 3, 4, and 5 are sectional uid in the chamber. As the construction of explosive engine cylinders with coolingchambers is well known in the art special description thereof is here unnecessary.

B is a tank which receives the water or cooling liquid. This tank should have an overflowpipe 1). Its top may be open or closed and provided wit-h an inlet through which it maybe supplied with the cooling liquid as occasion may require. The lower part of the supply-tank connects with the lower part of the cooling-chamber of the cylinder by a pipe O, and the upper part of the cooling-chamber of the cylinder communicates withthe upper part of the tank by a pipe D. Assuming the cock, hereinafter described, to be in such position (shown in Fig. 5) as to permit an uninterrupted passage through the pipe 0 from the tank to the cylinder and the tank being supplied with a suitable quantity of the cooling liquid, the latter passes through the pipe 0 into the cooling-chamber of the cylinder. As the latter is heated in the norof the explosive-engine, of which the cylinder forms a part, it ascends in the chamber and passes outat the top thereof through the pipe D, by which it is conducted into the upper part of the tank, so that a continuous flow of the liquid from the tank through the chamher and back again to the tank is established to carry away from the cylinder the too abundant heat thereof. Extended vertically from the pipe D is a vertical branch pipe F, which at its upper end is open to the atmosphere. The water rises in this pipe to the same level as in the tank and being open at top permits the escape of any steam which may form in the cooling-chamber by reason of the heat to which it is subjected in said chamber. To facilitate the free passage of the liquid from the cooling-chamber to the pipe D, a secondary pipe'Gis extended from the top of the cooling-chamber and joins the pipe D at a greater or less distance above, as shown in Fig. 1. This secondary pipe provides against the presence of dead or sluggish water in the upper part of the cooling-chamber and more or less out of the direct draft of the pipe D.

Provided in the pipe 0 is a three-way cock E, which is so constructed and arranged that when in the position shown in Fig. 5 its pasmal and well-known manner by the operation I communication against the cooling-chamber and simultaneously through its passages h 1 open communication between the outlet't' and the bottom of the tank, thereby permitting the outflow of the contents of the latter, and

that by turning it to the position shown in Figs 4 its passagcsfg It will open from both coolingchamber and tank to the outlet t to permit outflow from both simultaneously.

The requisite axial movement of the cock in bringing it to the several positions above set forth may be given to it by means of a rectangular knob 70, to which a wrench may be applied to turn the cock.

By the relative arrangement of the specified parts, as herein described, the tank and the cooling-chamber of the cylinder, either or both, may be emptied of the water or cooling liquid by simple manipulations of the cock. This emptying of the tank and of the chamber is frequently desirable as a precaution against freezing when the engine is idle in cold weather and when for any reason access to or examination of the said parts is desirable. By the use of the vertical branch pipe F any steam which may form from the cooling liquid during the operation of the engine is permitted to escape from the liquid prior to the passage of the liquid back to the tank, as set forth.

\Vhat I'claim as my invention is l. The combination with a cooling-chamber of an explosive-engine cylinder and a tank for supplying a cooling liquid thereto, of a pipe connecting the upper part of the coolingchamber with the upper part of the tank, a lower pipe connecting the lower part of the tank with the corresponding part of the cooling-chamber and having in it an outlet-opening, and a three-way cock provided in the said lower pipe and arranged as described to permit in one position the drainage of the tank, in another that of thejacket, in another that of both tank and jacket, and in a fourth the free circulation of the cooling water, in the manner specified for the purposes set forth.

2. The combination with a cooling-chamber of an explosive-engine cylinder and a tank for supplying a cooling liquid thereto, of a pipe connecting the upper part of the coolingchamber with the upper part of the tank and having a vertical branch pipe for the escape of steam, a lower pipe connecting the lower part of the tank with the corresponding part of the cooling-chamber, and having in it an outlet-opening,andathree-waycock arranged as described to permit in one position the drainage of the tank, in another that of the jacket,in another that of both tank audjacket, and in a fourth the free circulation of the cooling water, in the manner specified for the purposes set forth.
